I don't understand these two questions. Any help on how to figure this would be great. Thanks.
1. Write the equation for the decomposition of the hydrate, MgC*XH₂O
2. Write the equation for the decomposition of the hydrate, CuSO₄*XH₂O.
USUALLY, when asked to write the decomposition for hydrates, we mean to remove the water to make the anhydrous material but keep the remainder of the molecule intact. If that is the intent here, then
MgC*xH2O ==> MgC + xH2O
CuSO4*XH2O ==> CuSO4 + xH2O
Thank you for the help DrBob

Sure, I can help you understand how to tackle these questions. To determine the equations for the decomposition of hydrates, you need to know two things: the anhydrous compound and the water content in the hydrate.
Let's break down the process step by step:
1. For the first question: Write the equation for the decomposition of the hydrate, MgC*XH₂O
- Identify the anhydrous compound: In this case, it is MgC.
- Determine the water content: The formula indicates there are X number of water molecules in the hydrate.
To write the equation, you need to separate the anhydrous compound from the water molecules. In a decomposition reaction, the hydrate decomposes into the anhydrous compound and water.
The equation will look like this:
MgC*XH₂O(s) → MgC(s) + XH₂O(g)
Note that (s) represents a solid form, and (g) represents a gaseous form.
2. For the second question: Write the equation for the decomposition of the hydrate, CuSO₄*XH₂O.
- Identify the anhydrous compound: In this case, it is CuSO₄.
- Determine the water content: The formula indicates there are X number of water molecules in the hydrate.
Following the same steps as before, the equation would be:
CuSO₄*XH₂O(s) → CuSO₄(s) + XH₂O(g)
Again, (s) denotes a solid and (g) denotes a gas.
Remember, the X in the formulas represents the number of water molecules in the hydrate, and it can vary from hydrate to hydrate.
